Gliese 581g may actually NOT EXIST AT ALL

As I told you a couple weeks ago, Gliese 581g, planet of dreams, comes with a lot of uncertainty. It may, or may not, be habitable. It may, or may not, contain life.

And now, it may, or may not, exist.

Steven Vogt and his colleagues based the discovery of Gliese 581g on data taken from both their own research at the Keck Observatory in Hawaii and previously published data collected by the Geneva-based High Accuracy Radial velocity Planet Searcher (HARPS) team at an observatory in Chile.
